FIRE WEATHER PLANNING FORECAST FOR PUERTO RICO
NATIONAL WEATHER SERVICE SAN JUAN PR
401 AM AST TUE FEB 10 2026
DISCUSSION
FIRE DANGER WILL REMAIN LOW TODAY, BUT LOCALIZED RISKS WILL
PERSIST, SIMILAR TO YESTERDAY. LITTLE TO NO RAINFALL IS EXPECTED
OVER FIRE-PRONE AREAS, AND WHILE GUSTY WINDS ALOFT (15–20 KT) WILL
BE PRESENT, SURFACE WINDS WILL GENERALLY REMAIN BELOW 15 MPH.
MINIMUM RH MAY DROP INTO THE 40S–50S, BUT THIS ALONE IS NOT
SUFFICIENT TO SUPPORT CRITICAL FIRE WEATHER CONDITIONS. DESPITE
ABOVE-NORMAL RAINFALL OVER THE PAST 30–60 DAYS, FINE FUELS REMAIN
RECEPTIVE, AND KBDI REMAINS ELEVATED AT CABO ROJO (664) AND CAMP
SANTIAGO (580). CONDITIONS WILL CONTINUE TO BE MONITORED, BUT NO
SIGNIFICANT FIRE WEATHER CONCERNS ARE EXPECTED AT THIS TIME.
